Transcriber’s Note:
This book contains many words that use alternate spellings, are
misspelled, made-up, or obsolete. All were retained as printed.
Words and phrases in italics are surrounded by underscores, _like
this_.
Footnotes were numbered in sequence and moved to the end of the
section in which the anchor occurs.
Obvious printing errors were corrected, such as duplicate words, words
in the wrong order, upside down, backwards, partially printed or
unprinted letters and punctuation. Inconsistent punctuation (such as
commas contained inside close parentheses) was corrected.
Inconsistencies noted, but not changed:
Use of capitals and lower case letters for botanical names
Use of italics for “i. e.”
